During 2009, SUNON began to produce a new generation of fans to replace the popular series of KD (DC with sleeve or ball bearing) and KDE (DC with VAPO bearing). That it is really a generational change is also evidenced by the fact that new products have completely changed marking.

For decades, friction and noise have been the root defects for conventional fan motors. Usually after long-term operation, abrasions would be caused by the rub between the shaft and the inner surface of the bearing, creating the noise and sway common in many convention fan motors. Sunonwealth has been dedicated to the development of a new motor structure to breakthrough this impasse and root out the imperfections of conventional fan motors. From this commitment and background MagLev has come in to its own.
